With attractions ranging from painlessly educational exhibits, like the new interactive gallery where kids can perform their own hands-on scientific experiments, to a sublime exhibition on science in the 18th century, the Science Museum brings the subject alive for visitors of all ages. One of the three great South Kensington museums, it stands next to the Natural History Museum in a more modern, plainer building. Highlights include the Launch Pad gallery, which demonstrates basic laws of physics; Puffing Billy, the oldest steam locomotive in the world; and the actual Apollo 10 capsule. The six floors are devoted to subjects as diverse as the history of flight, space exploration, jet flight simulators, the large Hadron collider, 3-D printing, and (opening early 2017) the history of robots over the last 400 years. The Information Age gallery, devoted to communication networks including telegraph, television, mobile phones, and the Internet, was opened in 2014 by Queen Elizabeth,
who marked the occasion by sending her first tweet. Overshadowed by a three-story blue-glass wall, the Wellcome Wing is an annex to the rear of the museum, devoted to contemporary science and technology. It contains a 450-seat IMAX theater and the Legend of Apollo—an advanced motion simulator that combines seat vibration with other technical gizmos to re-create the experience of a moon landing. If you're a family of at least five, you might be able to get a place on one of the popular Science Night sleepovers by booking well in advance. Aimed at kids seven years old, these nighttime science workshops offer the chance to camp out in one of the galleries, and include a free IMAX show the next morning; check the website for details.
